The Sport Fucker Energy Ring is a TPR cock ring that is super stretchy. Because of this, you can easily wear it and take it off. TPR is also used by many manufacturers in the industry because it is safe and comfortable for users.
The multi-hole design delivers 3 main uses. It can be used as a c-ring and it provides good constriction to both promote enhancement and cum delay. The hole at the bottom can be used to drop in those balls. Also, with the addition of Trainer rings, you can do some ball stretching too. Split those nuts as well by putting each of them through the side openings instead of dropping them down.
